가빈이

목요일에 선생님의 오피스에 놀러 가고 가빈이가 최후로 봤다! 아기가 정말 귀엽다~~ 진짜 큰아기이군요! 많이 먹기 좋아하는 것 같아요. 많이 웃기도 좋아하고 행복한아기이에요!

(아이고...look at those cheeks><)

요즘 파이널하고 paper도 있고 힘들어 죽겠다 . 이제 다 긑내고 다행이다. 여름 방학은 이제 시작!

사촌이 결혼했다

우아ㅏㅏ제사촌 Joanne이가 결혼했어요! 사년전에 벨이징 대학에 공부하러 중국에가서 남편하고 중국에서 만나고 반했어요. 남편은 프랑스 사람인데 영어가 잘 못해요. 이제 진짜 결혼식 아니고 삼년 후에 프랑스에서 다른 결혼식 있을 거래요. 축하해요!! 프랑스 꼭 갈게요~!

Quadrant Denture class

지난 토요일에 UCLA dental school에서 quadrant denture class들었다. 저는 졸업한 다음에 치대 가고 싶기때문에 그랬다.

이곳에 simulation lab이에요! 일학년하고 이학년 학생들이 sim lab에서 많이lab work해야 돼요. 삼학년부터 진짜 환자를 봐요. 그래서 많이 연습하기가 중요해요. (Do lots of lab work/practice before starts working on real patients during the third and fourth year)

완성! 이게 제첫번째 denture입니다~ 여섯시간 쯤 걸렸어요.. 진~~짜 어려웠어요.ㅠㅠ 왁스를 사용할때 손이 탔어요.. 그렇지만 정말 재미있었어요!!

(had to have the correct bite/angle of teeth placement and everything..어려웠어요)

(also took my first impression!)

배드민턴

지난 금요일에 친구하고 배드민턴을 치러 wooden center에 갔다. 숙제가 많아서 midterms도 있고 스트레스가 너무 쌓였다ㅠ-ㅠ 우리 두시간 동안 배드민턴치고 저는 treadmill도 베리조금 했다ㅋㅋ 제research lab의 post-doc도 배드민턴치러 왔다! (사진에 남색옷하고 반바지 입은 사람)ㅋㅋㅋㅋㅋ 재미있었다~!! 운동한 후에 얼음 물을 마시는 것이 제일 느낌 인다! 운동 자주 안 해서 주말에 팔하고 다리 근육이 아팠다ㅠㅠ헐.. 앞으로 운동 많이 해야 될 것 같아.....ㅎㅎ

Modern Toilet

이 대만 식당이 너무 이상해요. 테마가 화장실이에요. 자리가 toilet처럼 그리고 테이블이 목욕통 이에요.

음식이 toilet-shaped bowls에 있어요..

아ㅏ...아이스 크림도 똥처럼 만들어요..

재미있나 봐요. 저는 대만에 갈때 꼭 가 볼 거예요ㅋㅋㅋㅋㅋㅋ

Lab 8: Census 2000/2010

The first two maps show the population distribution of African Americans in the United States according to the 2000 U.S. Census. From the two maps, it is apparent that the Black population is concentrated in the southeast region of the United States, with some counties that have as much as 86% of African Americans. This data makes sense considering the history of the South, but the maps also show that migration has taken place with people moving to northern parts of the United States.

The next two maps show the population distribution of Asians in the United States with data taken from the 2000 U.S. Census. The maps have a less apparent trend but they show that Asians are mostly populated on the West Coast, especially in major cities in California with the highest percentage being 46%. This is understandable because the West Coast is the closest to Asian countries, and many have decided to stay there once they come to America.

 

The last two maps were created using data from the 2000 U.S. Census and they show the population distribution of "Some Other Race" ranked by percent. The maps show that people identified as "Some Other Race" are mostly populated in the southwest regions of the United States, with the highest percentage being 39%. I would suspect that they are Latin Americans due to the fact that Mexico is the neighboring country.

I have learnt a lot about what GIS is and how useful and applicable it is to analyze and solve real-life problems. Even though this is a very interesting subject, it is very challenging and my experiences with GIS were not always pleasant. There were lots of times when I got really frustrated with saving data at different places and having to redo the whole thing, but overall I enjoyed the class.

Lab 7: Mapping the Station Fire in ArcGIS

The Station Fire in Los Angeles County started on August 26, 2009 and was fully contained on October 16, 2009 at at 7:00 p.m. The fire burned approximately 160,577 acres of land and destroyed 209 structures, including 89 homes. It was the largest fire in Los Angeles County and the tenth largest fire in California since 1933. The fire started in the Angeles National Forest and severely affected the cities around it.
The first map shows the perimeters of the Station Fire from August 29, 2009 to September 2, 2009 at many different times. The second map only shows the perimeters of the fire on August 29, 2009 at 2:48 a.m. and September 2, 2009 at 7:02 a.m. It can be inferred from the second map that fire tends to go up the slope by looking at the elevation changes. The fire went from the red perimeter upwards toward the purple mountain and its final position is depicted by the orange perimeter.

The Station Fire affected many of its surrounding cities which included La Cañada Flintridge, Glendale, Acton, La Crescenta, Littlerock, Altadena, Sunland, and Tujunga (Wikipedia). None of these cities are actually within the perimeters of the fire according to my second map, which shows how destructive the fire was as it could affect its surrounding cities as well. Many people in these cities were forced to evacuate and there were a lot of people in other cities that were affected by the smoke and the ashes in the air.
The theme of my map is the effects of the Station Fire on potential cities. Condor Peak is the only place that is fully within the perimeters of the fire, so I hypothesize that it would receive the most damage by the fire. The cities in the San Gabriel Valley below the fire would experience aftermath of the fire such as bad air quality caused by the smoke and ashes.

This week's lab is really interesting because I remember seeing the fire in the mountains from my home back in Arcadia, but I had never really thought about how the fire moved or how it affected its surroundings back then. I think it is incredible that ArcGIS can be used to analyze patterns and provide explanations for situations that happen in real life.

Lab 6: DEMs in ArcGIS

 

I chose to do this lab assignment on Grand Canyon because it is a famous attraction located in Arizona. It is a steep canyon carved by the Colorado River and known for its dramatic elevation changes. The geographic coordinate system used is the North American Datum of 1983. The extent information (in decimal degrees) of my original DEM is:

Top: 36.3608333326

Left: -112.540277777

Right: -111.69361111

Bottom: 35.9647222214

Lab 5: Projections in ArcGIS

 

Getting Started Questions:
How many degrees does the equator span?
360 decimal degrees
How many degrees do the northern- and southern-most graticule lines span?
180 decimal degrees

What do these two lines in fact represent?
These two lines represent the total distance in decimal degrees around the Earth latitudinally and longitudinally.

Approximately how many miles separate Washington, D.C. and
Afghanistan when crossing the Atlantic?
6,913.151 miles

Mercator Projection: 
Is Alaska really bigger than Brazil?

Yes

What about Greenland?

Yes

How far is Washington, D.C. from Kabul now?

10,110.689 miles 

Map projection is essential in creating maps as it allows a better understanding of the three-dimensional world by representing it on a two-dimensional surface. It also provides a more transportable model as well. Cylinders, cones, and planes are all used to create map projections. Map projections are constructed to preserve one or more of the map regions properties including area, shape, direction, bearing, distance, and scale. Different map projections exist depending on the purpose but no map can perfectly represent the surface of the entire Earth.

Equal area projections such as the Bonne projection and the Sinusoidal projection preserve area. They keep the areas on the Earth and their corresponding areas on the equal area map proportional. In other words, given any two regions A and B on the Earth and their corresponding regions A' and B' on the map, the surface ratios of A to A' and B to B' are the same.

Equidistant projections preserve distance from some standard point or line. These include the equidistant cylindrical projection and the equidistant conic projection. They maintain equal distances from the center of the projection to any other place on the map in all directions, but area is distorted as a result.

In conformal projections such as the Mercator projection and the Gall Stereographic projection, angles are preserved locally. The Mercator projection is the most widely-used conformal projection. It is a cylindrical map projection and is used for nautical purposes because of its ability to represent rhumb lines as straight segments. It is good for preserving the angles and the shapes of small objects, but it distorts the size and shape of large objects as the scale increases from the equator to the poles.

Map projection is the method of taking the surface of a sphere or other shapes and representing it on a plane. Inevitably, distortions occur during the transformation of a 3-D model to a 2-D surface and some information is lost in this process. Despite these perils, map projection is significant in creating maps and its variablility allows the user to choose and construct the best-possible representation of the desired model depending on the situation.

Lab 4: Introducing ArcMap

This week's lab was a lot more difficult than last week's lab exercise. While Googlemap was relatively straightforward and easy to understand, GIS was really difficult and confusing for me even with the tutorial.This further reinforces the point that neogeography is for amateurs while GIS is for professionals. Even though it is quite complicated to use, GIS has proven to be an effective and helpful mapping tool.

A problem I encountered while doing the lab was saving the data onto different computers, so when I opened my completed project on another computer some of the data and the graph were no longer present. I ended up having to redo the whole thing several times to finally get it right. Another problem I had was not being able to undo some of the things such as color changes and had to change it back manually.

GIS has great potential in helping users understand the spatial relationship between a place and its attributes through the use of maps. It lets users incorporate graphs and maps together to better understand and solve real-world situations. For example, the map for this lab exercise is used to help people understand the relationship between the airport noise and its surrounding population so that measures can be taken to solve this problem. GIS is extremely helpful in mapping out data, visualizing the relationship between data, and analyzing the data.

Despite its potentials, GIS contains certain pitfalls as well. First of all, GIS is not user-friendly for first-time users. A lot of steps have to be taken to perform a simple operation. The program can be very confusing for amateurs unless they go through the tutorial several times. Another downside of GIS is that it is not easily accessible by the public since the program is quite expensive. Therefore, GIS is mostly utilized by professionals and the government to understand real-life problems and develop ways to solve them.

Lab 3: Neogeography

View Sightseeing in Taipei Utilizing the MRT in a larger map

I chose to do a map on popular places in Taipei that can be reached utilizing the Taipei MRT (Municipal Rapid Transit). The traffic in Taipei is highly congested, making the MRT the most popular transportation because it is cheap, convenient, and accessible. The line connecting Taoyuan International Airport to Chiang Kai-Shek Memorial Hall Station shows the route that one must take by bus or taxi from the airport to the MRT station because currently there is no station at the airport yet. According to Taipei Times, "The MRT line connecting Taipei to Taiwan Taoyuan International Airport is scheduled to open in 2014." I chose Chiang Kai-Shek Memorial Hall to be the first stop because it is at the heart of Taipei. From there, one can take the MRT train to various types of attraction in Taipei, such as the famous Shilin Nightmarket or the Taipei Zoo.

Neogeography is the creating and sharing of maps to offer insight on a personal level. According to Turner (2006), neogeography is about “…people using and creating their own maps, on their own terms and by combining elements of an existing toolset. Neogeography is about sharing location information with friends and visitors, helping shape context, and conveying understanding through knowledge of place.” Neogeography offers insight on a more personal level than GIS in that the maps are drawn from personal experiences. However, this form of mapping can contain certain pitfalls. Unlike GIS, neogeograpraphy is used by amateurs, so the results can be a bit biased because people view things from different perspectives. The information presented by the maker can also be misleading because of misinterpretation. Nevertheless, neogeography has great potential because it is flexible and can be changed, whereas GIS is rigid. Neogeography lets people learn from other people’s experiences and gain valuable information from the world around them.

Lab 1: Maps

The "Marauder's Map" from the book "Harry Potter" is one of my favorite maps. It was created by James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew during their school days at Hogwarts. It is a magical map that gives a detailed layout of Hogwarts, including its hidden passageways and other mysteries. The map appears to be a blank sheet of parchment that is only activated when the user points his or her wand at the map and says, "I solemnly swear that I am up to no good." The map will return to its original blank state when the user says, "mischief managed." What I find interesting about the map is that it also shows where the people are located. The last picture above shows Albus Dumbledore pacing around in his room. The map is very trustworthy in that it cannot be fooled by disguises such as Polyjuice Potion and Invisibility Cloak. ( From the blog "99 Red Balloons" http://ninety9-redballoons.blogspot.com/2009/08/click-click.html)

This is a map of the Taipei MRT( Municipal Rapid Transit). The map shows the rail lines as well as the stations, letting travelers know which lines to take in order to go to their desired locations. The map also provides a key of the rail lines and their corresponding colors. What I find interesting about the map is that it also shows future lines in faded colors. According to Taipei Times, "The MRT line connecting Taipei to Taiwan Taoyuan International Airport is scheduled to open in 2014," which will be a lot more convenient for travelers because currently they have to take buses to go from the airport to other places. The MRT is a popular transportation in Taipei and is widely used by children and adults alike. ( From the blog "Memoirs on a Rainy Day" http://range.wordpress.com/2007/01/23/mrt-taipei-taiwan-status/)

This is a map of the Disneyland theme park. The map provides a general layout of the park and has drawings of the rides to allow people to easily find what they are looking for. The map uses numbers to designate where the restaurants and shops are in the park. It also has symbols of the restrooms and the telephones. What I find interesting about the map is that each of the eight themed areas ( Main Street, U.S.A., Adventureland, New Orleans Square, Frontierland, Critter Country, Fantasyland, Mickey's Toontown, Tomorrowland) has its own color, which makes it a lot easier for people to find the numbers in that area. The map also uses bold and vivid colors that appeal to the people. ( From "Chip & Company" http://www.chipandco.com/2010/01/disneyland-refurbishment-schedule-2010/)
